Frequently Asked Questions

Can you reheat these?

Yes, you can definitely reheat Potatoes Au Gratin. You can make this gratin ahead of time and heat it when you want to serve it.

Just cover the gratin with a layer of foil or an oven-safe lid and reheat it for about 20 minutes at 180 degrees Celsius.

Potato Au Gratin vs Scalloped Potatoes

Both these dishes use sliced potatoes and cheese, but they differ a bit from each other.

While in Gratin, sliced potatoes are covered with breadcrumbs and cheese and then baked until brown.

But in Scalloped Potatoes, the sliced potatoes are baked with heavy cream or milk.
Another minor difference between the two is the way, potatoes are sliced.

In both the dishes, the potatoes are cut into rounds and added into the casserole, but the potatoes used in scalloped potatoes are often cut a bit thicker than those in au gratin potatoes.

Which cheese is best to make this recipe?

Most of the people use Cheddar or Mozzarella Cheese to make Potato Au Gratin, but here I have used Gouda Cheese as it gives a nice smoky flavor that is loved by everyone at home.

If you like the strong flavor of blue cheese, you can use Stilton Cheese, Pepper Jack Cheese to give a hint of spice to your gratins or Gruyere Cheese for a nutty taste and melty texture. 

Which potatoes are best to make Au Gratin?

If you have an option to select from the variety of potatoes, always chose Russets Potatoes for the gratin; as they have the most starch and make the creamiest sauce.
You can use any potatoes for this gratin, even sweet potatoes taste great when used in this gratin.

If you are making Mashed Potatoes Au Gratin, you can opt for Yukon Gold Potatoes, they taste the best.

How to make Mashed Potatoes Au Gratin?

Try making a Mashed Potatoes Au Gratin instead of this classic recipe.
You just have to substitute flavourful mashed potatoes mixed with the sliced potatoes.

To make the mashed potatoes, you have to first cook the mashed potatoes along with chicken stock and garlic and then mix it with melted butter for the best taste.

How to prevent sauce from curdling?

If you use only milk to make this Gratin, there is a high chance that the sauce will curdle. The protein in the milk has a high chance of curdling. Once the temperature hits 180ºF and above the milk tends to curdle.

That’ the reason we add in the cheese, to make it extra creamy, which increases the fat and there are fewer chances of curdling.

Which Cheese to use for Gratin?

I have used a combination of Gouda and Cheddar, but you can even try other Cheese options such as Gruyere Cheese, Sharp Cheddar, Parmesan etc.

Serving Suggestions

Every household has its own way to serve gratin. I like to serve this cheesy Potato Gratin with slices of toasted homemade herbed bread for a light dinner.

But if you are looking for a wholesome meal, you can serve it along with Roasted/Grilled Chicken, Pan Roasted Steak, Pork Chops or any other similar dish.

You can also serve a light Italian soup or salad on the side with Au Gratin Potatoes.

Storage Suggestions

Potato Au Gratin freezes beautifully. Just airtight it with an aluminum foil or a plastic wrap so that air doesn’t go inside the container.

Freeze it for about 2 weeks, as beyond that it can become a little smelly.

Though, I would recommend you to make it fresh and enjoy, as this dish is very easy and quick to make.

Notes

You can make this dish in muffin tins and make individual portions.
Slice the potatoes into ⅛ inch thick pieces, so that they cook evenly.
Use both gouda and cheddar cheese, for extra creaminess and flavor.
Cover the gratin with foil while cooking, as it helps to gently cook the potatoes.
Remove the foil and cook for 10-12 minutes again, for that crusty top.
